Fig. 6 is a close said opening, a post carried by the other side view in open position. Figs. 7 and 8 are end of the link, the free end of the latch being details of a spring forming part of our invenformed with an opening to receive the end of tion. Fig. 9 is a side elevation of a clevis the post and the post being formed with a embodying our invention. Fig. 10 is a top side groove in its end, and a spring supported view of the same. Fig. 11 is a section on line longitudinally in the outer side of said latch v 2) of Fig. 10, and Fig. 12 is a section on line and extending through the post-opening and w w of Fig. 10. through the groove in the post.
